is mounted a short distance from the" rear f acezofthe guidebars12 Eachofthe guide barslflis provided with diagonally, disposed portion, asindicated. at 15 in Fig. 1, such diagonally disposed portion being sub-j'20 V upon-which thefly devices l lirotate.

The forwardendsof thearms-19 are notchedso as readily to receive thej lead edge o'flthepaper'in the-angle of the. notch, with the lower finger of the notch insuch posi-v tion insubstantial alignment with the as to providea supportfor the paper from underneath as'well as to'st'op the forward movementof the paper; By the provision of-the angularly arranged fingers forming'the 7 notch, a paper engaging the notch from-above is'hfeld in position'and the leadedge ofi the paper prevented from shiftingvin-position 'with'respect to the arm cluring the downward movement ofthe arm andpaper together for i the deposit of the paper upon thereceiver.

'For providing the desired movement of 7 the" stop arms 19, such armsarev slidably mounted in slide boxes 20 which in turn are mounteduponarock shaft 2l.so as,to swing vertically thereabout under. control of therock shaft.- The. means for controlling the j 7 position of the rockshaft 21 and for controlling thus the angular position of; the slideboxes 20 and itherstop ar'ms 19 comprises an v arm 22- carried by saidshaft at one end por- I tion thereof, being provided with a roller 23which engages a cam 24: mounted upon a drive shaft 25, such. shaft 25being thegshaft tion shown the shaft 25 being given a singlecompleterotation for each fifty papers passing between the rollers 10 and 11 tothe delivery apparatus.

For controlling the spect to the slideboxes 20, I have provided links 26pivotally connected at their upper a ends with the stop arms andpivotally con-" nected at their lowerends, withiarins 27 arising fromthe rock shaft 28which is pivotally, mounted in any suitable bearingsfinthe I longitudinal-i p'osition of the slidablyinounted stop'arms19withre-,

frameof the machine. 1 The position of the rock shaft 28 is controlledby a cam 29 11011 rotatably mounted withrrespect, to the shaft 25,such'cam actingupon the shaft28through the medium of a roller-30"carried byan arm 7 31 mounted upon theshaft 28, such rollerengaging theface of thelcam 29. I

With the parts in fthe'positionas trated in Fig. 1, and with. the flydevices 'l and the shaft25 and its drivenparts rotating incounter-clockwise direction in said Fig.1, the stop armslfil. are heldout of thfpathof thepapersj passing along the face oftheguide c bars 12;A very short time thereafter, the part-s willihave assumed the positionshown" in Fig. 3, with the roller123 in contact'with.

When the paperfreaches its normal engagingposition at the angle of the notch in the stop arm, such paper is underthe control determined position on the receiver different from thatatwhich the adjacent preceding along theprescribed path to a"definitepre-' by 1 of the arm so that upon subsequent down-, ward movement ofthe arm, the paper is led paper wasf deposited on the receiver. In theconstruction illustrated, such downward movement. of." the: arm with thepaper is broughtabout byreason of thepassa'ge of the position shown inFig. 4, with a paper .being, held in changed position upon the belt. 17as compared to theposition taken by theynext 'tion as shown in Fig; 5.parts have assumed the position shown in i Fig. 5, the roller 23controlling the position preceding: papers thereon, the delivery o-f thepapers downwardly continues, the following papers being piled on thearms 19 adjacent'to. the guide bars 12;and extending partially overthetop face of'thedisplaced paper so as to weightit down and prevent itsmovement-with respect to the adjacentpapers.

After one or morepapers have been deposited on top of the displacedpaper so as to render further presence of the arms adjacent to thereceiver unnecessary, the arms 1 are slowly withdrawn by a movementbackwardly underneath the papers piled thereon soas to deposit suchaccumulatedpapers on thereceiver. Such movement of the arms is effectedby the engagement of the roller with a rise of the cam 29 for moving thearm '27 toward the right in said Fig. 4, serving to movethe stop arm 19gradually from the po sition shown in Fig. 4 to the retracted posi-Shortly after the of the shaft 21 engages the'rise34 of the'c'am 24causing the'slide boxes 20'and the stop arms19 to be swung about theshaft 21 into the position as shown'in, Fig. 6, which corresponds withtheangular position of the boxes and the stop arms as shown in Fig. 1.Shortly thereaftentheroller 30"passes out of engagement with the rise ofthe cam 29,:per-

mitting a spring 27 as shown in Fig. 1 to swing the arm 27 toward: theleft in Fig. 6 again tothe position as shown in Fig. 1, and

causing the stop arms '19 to reassumethe pos-ition as shown in Fig. 1. 1

From the above description, it will-be seen that normally the stop armstands in the position shown in Fig. 1; that at a predeter- V mined timein the rotation of the cam, 24 the stoparm swings downwardly to theposition shown in Fig. 3 where it serves by contact with the forwardedgeof: a'paper to stopthe downward movement ofsuch paper; that im:

The movement of the changed positionpaper serves to insure that the .positionof the papers shall'be changedvery little if any at all by the withdrawal of theb'elt. V I o I As isclearly shown in Fig. 1, the opposite sides of the cam 24 are formedsimilarly.

That is to say, at each side thereof the cam 24 is provided with a step32, a'still lower step 33 and arise 34. lSuch arrangement is providedfor use in case it is desired to divide the papers into unit piles of 25rather than unit piles of 50. For the normal operation of the device asfirst above described, a shield- 37 is removed and replaced in anopening. 38

While I prefer to employ a construction '35 pivotally mountedupon a pin36 is prosubstantially as shown in my drawings and f as above described,it is to be understood that my invention is not limited to thatparticular form except so far, as the claims are so limited by the priorart, it being understood that changes nay'well bemade in theconstruction shown'without departing from the spirit'of my invention. r
